Modifications:

Modified by CorAL on 2025-01-10:
1. modified the naming to prevent conflict with the original project.
2. Remove posix docking, compatible with other platforms.
3. removed esp-idf related dependencies.
4. trimmed termios and other functions.

xf_err_t xf_vfs_register_common	(	const char *	base_path,
		size_t	len,
		const xf_vfs_t *	vfs,
		void *	ctx,
		int *	vfs_index
	)

Register a virtual filesystem.

参数

base_path	file path prefix associated with the filesystem. Must be a zero-terminated C string, may be empty. If not empty, must be up to XF_VFS_PATH_MAX characters long, and at least 2 characters long. Name must start with a "/" and must not end with "/". For example, "/data" or "/dev/spi" are valid. These VFSes would then be called to handle file paths such as "/data/myfile.txt" or "/dev/spi/0". In the special case of an empty base_path, a "fallback" VFS is registered. Such VFS will handle paths which are not matched by any other registered VFS.
len	Length of the base_path.
vfs	Pointer to xf_vfs_t, a structure which maps syscalls to the filesystem driver functions. VFS component doesn't assume ownership of this pointer.
ctx	If vfs->flags has XF_VFS_FLAG_CONTEXT_PTR set, a pointer which should be passed to VFS functions. Otherwise, NULL.
vfs_index	Index for getting the vfs content.

返回: XF_OK if successful. XF_ERR_NO_MEM if too many VFSes are registered. XF_ERR_INVALID_ARG if given an invalid parameter.

const xf_vfs_entry_t * xf_vfs_get_vfs_for_path ( const char * path )

Get vfs fd with given path.

参数

path	file path prefix associated with the filesystem.

返回: Pointer to the xf_vfs_entry_t corresponding to the given path, which cannot be NULL.

const xf_vfs_entry_t * xf_vfs_get_vfs_for_index ( int index )

Get vfs fd with given vfs index.

参数

index VFS index.

返回: Pointer to the xf_vfs_entry_t corresponding to the given path, which cannot be NULL.
